Apps Script Utilities.parseCsv assumes new row on line breaks within double quotes

Question

When using Utilities.parseCsv() linebreaks encased inside double quotes are assumed to be new rows entirely. The output array from this function will have sever

Answer 1

To avoid trying to understand regular expressions, I found a workaround below, not using Utilities.parseCsv(). I'm copying the data line by line.

Here is how it goes:

If you can find a way to add an extra column to the end of your CSV, that contains the exact same value all the time, then you can force a specific "line break separator" according to that value.

Then, you copy the whole line into column A and use google app script' dedicated splitTextToColumns() method...

In the example below, I'm getting the CSV from an HTML form. This works because I also have admin access to the database the user takes the CSV from, so I could force that last column on all CSV files...

function updateSheet(form) {
  var fileData = form.myFile;
  // gets value from form
  blob = fileData.getBlob();
  var name = String(form.folderId);
  // gets value from form

  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = ss.setActiveSheet(ss.getSheetByName(name), true);

  sheet.clearContents().clearFormats();

  var values = [];
  // below, the "Dronix" value is the value that I could force at the end of each row
  var rows = blob.contents.split('"Dronix",\n');

  if (rows.length > 1) {
    for (var r = 2, max_r = rows.length; r < max_r; ++r) {
      sheet.getRange(r + 6, 1, 1, 1).setValue(String(rows[r]));
    }
  }

  var spreadsheet = SpreadsheetApp.getActive();
  spreadsheet.getRange("A:A").activate();
  spreadsheet.getRange("A:A").splitTextToColumns();
}
